Solar Activity
.24 hr Summary… Solar activity was very low. The solar disk remained spotless and no Earth-directed CMEs were detected in available satellite imagery.
.Forecast… Solar activity is expected to be at very low levels on 04-06 Dec.
Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels.
.Forecast… The greater than 2 MeV electron flux is expected to persist at normal to moderate levels on 04-06 Dec. The greater than 10 MeV proton flux is expected to persist at background levels throughout the period.
Solar Wind
.24 hr Summary… Solar wind parameters reflected nominal conditions under an ambient solar wind regime. Total field strength averaged 2-3 nT while the Bz component varied between 3 nT and -3 nT. Winds speeds began the period near 350 km/s and steadily decreased to end the period just over 300 km/s. The phi angle was predominately in a positive orientation.
.Forecast… Solar wind parameters are expected to remain nominal on 04-06 Dec.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be mostly quiet on 04-06 Dec.
